Question 1: Differentiate between the following terms.
  1. Frequency spectrum and bandwidth.
  2. Bandwidth and throughput.
  3. Bit interval and bit rate.
Answer:

Frequency Spectrum / Bandwidth

Frequency Spectrum of a signal is the collection of all the component frequencies it contains. It is shown using a Frequency domain graph.
Bandwidth: of a signal is the width of the frequency spectrum
In other words, Bandwidth refers to the range of the component frequencies and Frequency Spectrum refers to the elements within that range.
Measurement of how fast data can pass through a point o In other words, if we consider any point in the TX Medium as a wall through which bits pass, then throughput is the number of bits that can pass this wall in second

Bit Interval and Bit Rate

Most digital signals are aperiodic and thus Period and Frequency are not the appropriate terms to describe them

Bit Interval (seconds)

Time required sending one single bit

Bit Rate (bps)

Number of bits sent per second
